Application filed. November 22, 1919. Serial No. 340,055.

To all whom it may concern:

Be it known that I, HERBERT GREcsoN, a citizen of the United States, anda resident of Weehawken, in the county of Hudson and State of NewJersey, have invented a new and Improved Tobacco-Pipe, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new and improved tobaccopipe arranged to prevent burning out of the base of the bowl and thuinsuring long life of the pipe.

Another object is to provide a chamber for the reception of the nicotinto prevent the latter from passing into the pipe stem and to the mouthof the smoker.

Another object is to provide an even draft in the base of the bowl andthus insure a proper uniform burning of thetobacco and consumption ofpractically all the, tobacco with which the bowl is filled by the user.

With these and other objects in view, the invention consists ofv certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specificatiorn' in whichsimilar characters of reference indicate corresponding parts in alltheviews.

Figure 1 is a longitudinal sectionalelevation of the improved tobaccopipe with the stem and portion of the stummel shown in elevation;

Fig. 2 i a plan view of the bowl and a portion of the stummel; and

Fig. 3 is a longitudinal sectional elevation of a modified form of thetobacco pipe, with the stem and part of the stummel shown in elevation.

The tobacco pipe illustrated in Figs. 1 and 2 comprises essentially abowl 10 having an integral stummel 11 connected with the stem 12terminating in the mouthpiece 13. In the base of the bowl 10 is arrangeda centrally disposed protuberant member 15 having a rounded off top andforming with the wall of the base portion of the bowl 10 an annulardraft chamber 16 connected with the bore 17 of the stummel 11. The bore17 enters the annular chamber 16 a distance above the bottom of the bowland a distance below the top of the protuberant member 15.

By the arrangement described the upper portion of the protuberant memberforms a support for the tobacco with which the bowl 10 is filled by theuser so that the tobacco does not free the annular chamber 16 but leavesthe latter practically unobstructed. The bottom ofthecharge of tobaccousually extends a short distance below the top of the protuberantmember'15 but does not reach to the bore 17, and hence when the pipe'l1n use a uniform draft is had in the chamber 16 to insure uniformburning of the tobacco in the bowl 10. It will further be noticed thatby the arrangement described the base portion of the bowl 10 is notsubjected to the burning action of the tobacco and hence the base of thebowl is not liable to be burned out and consequently long life of thepipe is insured. It will further be noticely that the bottom portion ofthe annular chamber 16 on account of being below the bore 17 allows thenicotin to accumulate therein and hence nicotin is not liable to passthrough the bore 17 to the mouth of the smoker. A further advantagederived from the construction of thebowl as set forth i that the tobaccocan practically be all burned and hence no tobacco is wasted.

In the modified form shown in Fig. 3, the bowl 20 is provided at thebottom with a threaded reduced portion 21 which screws into the base 22from which extends the stummel 23 connected with the stem 24:. The bowl20 is provided in its base portion with a centrally arranged protuberantmember 25, similar to'the'protuberant member 15 above referred to, andforming an annular chamber 26 with the wall of the bowl 20. From thebottom of this chamber 26 leads a bore 27 to the bottom of the reducedportion 21 and this bore 27 connects with the bore 28 formed in the base22 and stummel 23. The functions of the protuberant member 25 arepractically the same as above described in reference to the protuberantmember 15 and the bowl 10, and hence further description of the same isnot deemed necessary.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a tobacco pipe, a bowl provided at its base witha centrally disposed protuberant solid member forming with the wall ofthe bowl an annular draft chamber from which leads a bore connected withthe pipe stem, the said bore opening into one side of the said annulardraft chamber above the bottom thereof and a distance below the top ofthe said protuberant member.

2. In a tobacco pipe, a bowl provided with a stummel and a stemconnected with the stummel and provided with a mouthpiece, the said bowlbeing provided in its base with a centrally disposed protuberant memberintegral with the base and rising therefrom, the said protuberant memberforming 10 with the wall of the base portion of the bowl an annulardraftchamber, the said protuberant member being solid and rounded off at thetop, the said stummel having a bore leading into one side of said draftchamber 15 at apoint intermediate the top and bottom of the said draftchamber.
